Too many to list. I don=E2=80=99t know who is =E2=80=9Cwinning=E2=80=9D =
in market share right now, as I am sure each vendor tracks their wins =
differently.

There are definitely a few making more noise than others.

Hello Kasper,
I will do my best to answer your SD-WAN question, but as you mentioned =
it is a buzzword that has a bit of confusion in its definitions. I =
would say that a SD-WAN solution should have the following elements:
1.) Ability to manage multiple WAN connection and choose the path based =
on user and machine criteria (The Hybrid WAN)
2.) A controller to manage the polices and operations of the SD-WAN =
devices
3.) Analytics on the network and application level
4.) A software overlay that abstracts and secures the underlying =
networks
Currently there are a lot of solutions out there by many vendors. Some =
do all of these and some a subset, so it make the landscape a bit =

talking about Hybrid WAN (multiple connections) or WAN optimization.

Hi,
I'm not sure if the buzzword SD-WAN is used to compensate for another =
buzzword that got over-utilized (SDN) or it is a true 'new and improved'
way of doing things that has some innovation into it.
I heard different explanation from different vendors:
1) appliances (+ controller) placed in-line to put traffic in tunnels =
based on policy, with some DPI and traffic tagging...(to do =
performance/policy based routing) over an expensive link (MPLS) and a =
cheap one (broadband) with some 'firewall-like' filtering capabilities.
2) same as above, with a flavor of 'machine learning' to find a pattern =
for traffic to optimize utilization.
3) a controller that instantiates and tears down tunnels from 'classic =
routers' based on external policies and Network based features to do =
performance based routing over an expensive link (MPLS) and a cheap one
(broadband) with encryption.
Is the above a decent high-level summary?
Has anyone tried any of these solutions, any general feedback ?
Cheers,
Kim
